LIGHT BEAM SCANNING SYSTEM, DISTANCE DETECTION APPARATUS, AND ELECTRONIC DEVICE

摘要

A light beam scanning system, a distance detection apparatus (100), and an electronic device, the light beam scanning system comprising: a light source (1), a scanning module (2), and a light beam transformation module arranged in sequence along a light propagation direction, the light source (1) being used for emitting light beams; the scanning module (2) is used for sequentially changing the light beams emitted by the light source (1) to be emergent in different propagation directions, forming a scanning field of view; and the light beam transformation module is used for changing the emergent light beams from the scanning module (2) to stretch or compress the scanning field of view in at least one direction. The light beam scanning system can implement large light spot large field of view coverage in a specific direction; the demands for the aperture size of the light source (1) and the scanning module (2) are not high; and the control system has a simple structure and can achieve a large scanning range.
